Abstract

The FUJIX SCANART 450 is a monochrome film making scanner developed by FUJI fully utilizing its advanced scanner concepts. Salient features ofthis scanner include the following: 1) Large-sized originals (up to A2 format) can be processed at a high speed of4.5 mm/sec, thus providing enhanced productivity. 2) The scanner meets the highest level ofimage quality demanded in the field ofgraphic arts. 3) To allow for future system expansion, the input scanner has been separated from the output recorder. It is well known that a high level of image quality is required in graphic arts applications, with particular importance being attached to tone reproduction and sharpness in this field. It is also imperative to rule out the possibility ofany noticeable streak or non-uniformity in images. To meet these requirements, we have developed an input scanner employing CCD line sensors and an output recorder based on the laser diode, fully utilizing our accumulated know-how in the field of high-quality image processing technology. This paper discusses the technologies that have been established to take advantage of the features of the CCD. Chiefly among these are firstly, a technology to accommodate originals of large size, to provide the capability to read originals of A2 width (452 mm) with high resolutions; and secondly, a technology to achieve high imagee quality through the implementation of high accuracy compensation for CCD signals.
